To all whom 'it may concern. t

lle it known that l, Gnonoiis BAUJARD, a

Acitizen ofthe French Republic, and a resident of Paris, France, have invented certain Improvements in toinizers, of which the, following is a specification.

rlhis invent-ion relates to certain improvements in aton'iizers such as are particularly designed and adapted for employmentin connection with internal combustion engines and the like,- and has for its object to provide a device of this character 'of a coinparatively simple and inexpensive nature, and of a compact and durable construction, capable of employment for producing a substantially.complete atoniization of the charge in ainanner calculated to afford effective protection againstthe supply of liquid fuel to the combustion chamber of the engine or other appliance in connection wherewith the iii'iproved atoinizer employed and which -shall present certain features ot' Inovelty and improvement, whereby the atomizer is rendered capable of being ettectively used for the supply of ditterent liquid fuels, or in connection with eiig'iiies or equivalent devices of different types and capacities. The invention consists in certain novel features of the construction, and combinations and arrangements of the several parts of the improved atomizer, whereby certain important advantages are attained, and the device is rendered simpler, less expensive and otherwise better adapted and more convenient and effective for use,all as will be hereinafter fully set forth.

rlhe novel features of the invention will be carefully defined in the claims.

ln order that my improvements may be the better understood, I will now proceed to describe my invention with reference to the accompanying drawings, wherein- Figure l is a side elevation showing an atomizer constructed according to my invention, disconnected from the motor and from the fuel and air supply in connection wherewith it is ordinarily employed; Fig. 2 is a sectional view taken vertically and axially through the improved atoinizer, and illus trating the internal lstructure thereof; Fig. l is a partial underside view of the atoiiiizer :onstructed as shown in Figs. 1 and 2; and ig. 4 is a detached perspective view illusrating the formation of the removable or interchangeable controlling member or plug forming part of my improvements.

As shown in these views, the atoniizer is provided with a metallic body portion or casing l, of appropriate contour, having a central vertically extended cylindrical portion from one side of the central part whereof is extended an externally Screw-threaded discharge nozzle 3, integrally connected with the casing or body portion, and adapted for detachable screw connection with the wall of the cylinder or combustion chamber of the motor wherewith the atoinizer is to be used in such a manner as to discharge the conibustiile inixture thereto. A

The upper extremity of the cylindrical part 9. of the casing or body portion l is internally screwahreaded, as shown at to receive a removable screw plug or connection 5. the upper extremity of which is externally screwahrezuled for connection with a pipe leading to a source of fuel supply, and said plug or ti'onnectioin is provided with an axial bore (t through which the liquid fuel conveyed by such supply pipe is to be led within the casing or body portion to the inclosed vaporizing or atoinizing devices as will be hereinafter explained. 7 represents a ialve controlling the admission of such liquid fuel by way of said passage G, and 8 represents a spring connected with said valve in such a manner as to exert its tension to lift the valve and normally hold the same closed anl in contact with its seat, whereby the admission of the liquid fuel into the casing or body portion is normally prevented.

At the side of the cylindrical portion 2 opposite to the nozzle or connection 3, the casing or body portion is also provided with a centrally positioned internally screwtlireaded nipple t), wherein is engaged a tubular screw connection or coupling 10, having an axial passage l1, and provided with a screw-threaded extremity adapted for connection with a pipe or the like leading to a reservoir containing compressed air, whereby such compressed air is convcyed within the casing or body portion 1 for the formation of the combustible charge therein as will be hereinafter explained.

1:2 represents a valve which is inclosed within the coupling member 10 and is pressed by a spring 14 into seated or closed position in such a way as to normally prevvent the admission of the compressed air through the passage 11 into the casing' or body portion 1. As herein shown, said spring has its end opposite to valve 12 seated within a cup 15 arranged at the central part of tbe nipple 9, and provided with lateral ports 1G through which the air from passage 1l is admitted into its interior when valve 12 is opened.

17 represents a cylindrical bore produced axially within the vertically directed cylin-V drical central portion 2 -of the casing or body portion 1, the upper end of said axial bore 17 being in conmiunication with the screw-threaded passage et at theupper end of said cylindrical portion Q, so that free aecess is permitted thereto when the screw plug or coupling member 5 is withdrawn, and 1S represents a conical or flared discharge passage produced within the. discharge nozzle or connection 3, being extended at right angles from said bore 1T, with which it has comnnmication at its smaller end, while its larger or expanded extremity is adapted for com'nnmieation with the cylinder or combustion chamber of the motor in sach a manner as to convey and discharge the vaporized or atomized fuel thereinto with a minimum of condensation and resistance. The flared or conical bore or passage 1S within the discharge nozzle 3 is in axial alinelnentwith the passage 11 within the air connection 10, and the wall of the axial bore 17 within the cylindrical portion 2 is apertured as shown at 19 at a point diametrically opposite to the smaller end of said conical bore or passage 1S and in aline` nient therewith and with the compressed air passage l1, so as to permit the tlow of such compressed air as may pass the valve 12 along a substantially straight passage to and through the discharge nozzle, subject to regulation by improved controlling` means housedin the vertically directed bore 1T, as will be hereinafter explained. Such controlling or regulating means comprises, as herein shown, a removable plug or controlling member 22, provided at its upper end with a cylindrical body portion or head. as clearly shown in F 2 and ,l, of a diameter adapted to fit snugly within said cylindrical vertical bore 17, while being capable of removal through the screw-threaded opening` 4 at the upper extremity of the vertically directed cylindrical portion 2 of the casing l, upon removal of the screw plug 5 therefrom,

the lower end of said plug or controlling member 22 being reduced in diameter to produce a rounded axially extended stem pendent below the head or enlarged upper end of the controlling member, and adapted to lit snugly within a correspomlingly formed cylindrical bore 20 produced at the lower end of the cylindrical easing poition 2, and open at the underside thereof as shown in Figs. 2 and 3, its'lower extremitybeing centrally bisected by a transversely extended detent stripl countersunk in the .lower surface of the casing portion 2, and capable. of engagement between vforks or bifurcations Q6, 2G produced at the lower end of the reduced stem 25 of tlse controlling member .22 in such a manner as to effectively prevent turning movement of said member Q2 within the bore 1T when' positioued therein for use. The forked or bifurcated lower extremity of said stem is of such a length as to depend below the under surface of the casing portion 9 when that the fingers may be engaged therewith to conveniently push the incmber :'22 upwardly when it is desired to remove the same from the casing or body portion of the atomizer.

23 represents a bore or passage produced transversely and diametrieally through the enlarged upper head portion of the controlling member 22, in such relation to the forks or bifurcations 26, QG as to be accurately maintained thereby in axial alinement with the passages 18 and 19 at diametrieally opposite sides of the wall of the bore 1.7 wherein said member Q2 is inserted for use, so that the compressed air admitted by way of the passage ll under control of the valve l-'l is conveyed through said bere. or passage 23 of the controlling member and discharged 4into the smaller end of said tapered or'cenieal passage 1S, and t-t represents a duct or passage produced axially in the upper extremity of said member Q2 and adapted to receive the liquid fuel admitted to the casing by way of passage G under control by valve 7. the lower end of said duct or passage-'2l being in coinnmnication with the central part of the transverse passage or bore 23,;0 that central part of said bore or passage :23 in order that it may be acted upon by the air coursing therethrough when valve 14 is opened, in order that such admitted liquid fuel may be effectively vaporized and atomized by the operation of such air in such a luanner as to produce an extremely light and fluid combustible charge when such air is permitted to expand within the tapered bore or passage 1S of the discharge nozzle 3.

ln adapting my improvements, in the form above. described to dii'erent sizes or types of motors. and the like. and to different kinds of fuels, the passages and 2l within the controlling member should, if the best results are to be attained, be made in properly calculated diameters so that th(l proper volumes of air shall be supplied fol vaporizing o atomizing the desired volume: of fuel, and the removable character of th plug or member 2Q is particularly wel adapted for this purpose, since it permits o member 22 is in position within bore 1T, so

the admitted liquid fuel is conveyed into the i asf,

alo

changing the plugs or members 22 in order to adapt the one atomizer to different engines or for use with different kinds of fuel.

In the use of my improvements, as herein set forth, the liquid fuel may be discharged through the passage 6 at proper times by the operation 'of a pump timed with the motor in a Wellltnown Way, and the structure is such that the pressure produced within the cylinder or combustion chamber of the motor by the explosion of the charge will normally operate to reinforce the action ofthe springs 8 and Msc as to effectively close the passages 6 and 11 against the entry of fuel and air except at' such times as the pressure within such combustion chamber or cylinder of the motor shall fall after having been exhausted of the spent gases, ivh'ereupon the air and fuel are permitted to enteill^ through their appropriate passages, in order that the fuel may be atomized or vaporized to produce the fresh charge to be supplied to the motor, as above set forth. i

F rom the above description of my improvements, it will be seen that the atomizer constructed according to my invention is of an extremely simple, and comparatively inexpensive construction, and isparticularly well adapted for use by reasoi of its novel, improved and compact character, and it Will also be obvious from the above description that the device is susceptible of considerable modification without material departure from. the principles and spirit of the invention, and for this reason I do not desire to be understood as limiting myself to the precise formation and arrangement of'its several parts herein set forth in carrying out. my invention in practice.
